I don't live in North America. Looking to buy one of these but concerned with how the stock stones will handle M390. I have a bunch of kitchen knives with softer steels but my folders are in M390. Can the EP waterstones do anything here? And what does this mean (seller description for the Hapstone):
"Basic kit. 3 Hapstone silicon carbide sharpening stones: 220, 400 and 1200 grit
Simple stones for studying the basis of knives sharpening.
Not suitable for steels with hardness greater than 56hRC. It has soft ceramic bunch, it erases quite quickly."
For the "upgraded" kit, that just includes two more SiC stones (same silicon carbide stones from what I can tell) it says this:
"5 Hapstone silicon carbide sharpening stones: 120, 240, 600, 1000 and 2500 grit
The stones are made of silicon carbide and are designed for the hardest steels (up to 65 HRC). All stones are 6 mm thick and mounted on high-quality aluminium blanks."
Thanks!
